PLEASANT PUFF OVERDRAFT PIPE Filed Oct. 50. 1942 JOHN 3. SWAN.

Patented May 18, 1943 UNITED STATES PATENT OFFICE 2,319,756 PLEASANTPUFF ovEnnaAFr rrra John B. Swan, Gladstone, Mich. Application Octoberso, 1942, Serial No. 463,960 1 Claim. (01.131-202) This inventionrelates to a pleasant puff overdraft pipe.

An object of the invention is the construction of a novel pipe wherebythe user can enjoy a pleasant smoke, by reason of a novel absorbentdevice being used in the pipe, with means for causing the tobacco toburn with reasonable freedom, which altogether produces ideal results.

Another object of the invention is the construction of a novel absorbentdevice in a pipe, which will prevent objectionable juices or the likefrom being drawn into the mouth of the smoker or user.

A still further object of the invention is the construction of a noveloverdraft pipe which is comparatively inexpensive to manufacture,efiicient in operation and of a long life.

With the foregoing and other objects in view, my invention comprisescertain novel constructions, combinations, and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawing, and more particularly pointed out in the appended claim.

In the drawing:

Figure 1 is a view partly in elevation and partly in longitudinalsection of a pipe constructed in accordance with the present invention.

Figure 2 is an enlarged sectional view taken on line 22, Figure 1, andlooking in the direction of the arrows.

Figure 3 is a perspective view of the absorbent device, without thecheese cloth or cotton batten unit thereon.

Figure 4 is a plan view of a piece of cotton batten, while Figure 5 is asimilar view of a piece of chee e cloth.

Referring to the drawing by numerals, in which drawing I have shown thepreferred embodiment of my invention, I designates the bowl, which isprovided with an integral laterally-extending neck 2. The bowl I is alsoprovided with an inlet aperture 3, which permits air to be drawn intothe bowl by the user, whereby the tobacco burns comparatively freely,without going out; so often smokers are annoyed by the fire or burningtobacco dying out, but this is practically eliminated in my improvedpipe.

An overdraft tube 4 extends into the bowl I, the inner end of said tubeterminating approximately one-eighth of an inch from the bottom or innerface of thebowl. The outer end of tube 4 extends into the neck 2 nearits outer end. A detachable mouthpiece 5 has a reduced that registerswith the outer end of overdraft tube 4, Fig. 1, whereby the smoke isdrawn from thebowi into the mouthpiece through said overdraft tube 4. I

An absorbent device 8 is placed in the pipe, as clearly shown in Figurel, for the purpose of absorbing the moisture or juices that ordinarilycollect in the bottom of a pipe. This novel absorbent device 8 comprisesa coil spring body 9. the outer coil 10 being provided with a sharpimpaling point II; the inner coil l2 terminates in an elongated integralhandle l3, which handle is on a line with the central longitudinal axisof the coil spring body 9. This admirably places the handle in positionto be easily inserted and centers in the mouthpiece 5, as.clearly shownin Figure 1. The elongated handle l3 terminates at its outer end in anintegral elongated loop grip I4. When the mouthpiece 5 is detached fromthe neck 2 the operator can secure an eflicient grip on the absorbentdevice at It to remove the absorbent device, or to insert it, after ithas been removed from the assembled position. I place an absorbent pieceor sheet upon the coil spring body, such as cotton battin l5 or cheesecloth l6. The unit I5 or IE is best wrapped upon the coil spring body byimparting rotary movement to the body thereby impaling an end on thepoint II and then continuing rotary movement to the'body, therebywinding the sheet around lightly until enough has been wound on to fillthe neck 2 of the pipe, then press all around the coilspring body 9until the winding of the absorbent unit is pressed in between the coils;this presses down the wrapping so it comes nearly together, or entirelyso, on the inside of the coil, making an excellent filter or absorbent.The impaling point II is near the center longitudinal axis of the body9, whereby the absorbent unit I5 or I6 is admirably placed and held forthe wrapping function. f

I plan on having preferably six of the absorbent devices 8 (Fig. 3) witheach pipe sold, so

the smoker can take out his absorbent device or filter, every night, andby putting it in vinegar a few hours, it will rinse out easily.Therefore, the user of the pipe can have a clean absorbent device everyday, at a very small cost and little effort.

he will obtain an ideal smoke.

While I have described the preferred embodiment of my invention, andillustrated the same in the accompanying drawing, certain minor changesor alterations may appear to one skilled in the art to which thisinvention relates, during the extensive manufacture of the same, and I,therefore, reserve the right to make such alterations or changes asshall fairly fall within the scope of the appended claim.

What I claim is:

. Asa new article of manufacture, an overdraft pipe provided with anabsorbent device, said absorbent device comprising a body of a series ofspring coils, said body having its outer coil parallel throughout itslength with the other coils and terminating in a sharp impaling point 4turned inwardly near the longitudinal axis in convolution with the restof said coil, said body having its inner coil terminating in an integralelongated handle, said handle extending or centered with thelongitudinal axis of said body, said handle provided at its outer endwith a horizontal elongated loop grip, and an absorbent sheet impaled onsaid sharp point by rotating said body, whereby the sheet .is rolledaround the whole of said body with portions of said sheet within spacesformed by said coils and also covering the exterior surface of saidbody.
